Fairway wood center of gravity projection

Abstract

A golf club head includes a body defining an interior cavity. The body includes a sole positioned at a bottom portion of the golf head, a crown positioned at a top portion, and a skirt positioned around a periphery between the sole and crown. The body has a forward portion and a rearward portion. The club head includes a face positioned at the forward portion of the body. The face defines a striking surface having an ideal impact location at a golf club head origin. Embodiments include club heads for a fairway wood that at least one of a high moment of inertia, a low-center-of-gravity, a thin crown and a high coefficient of restitution.

What is claimed is: 
     
       1. A golf club head, comprising:
 a body defining an interior cavity, a sole portion positioned at a bottom portion of the golf club head, a crown portion positioned at a top portion, and a skirt portion positioned around a periphery between the sole and crown, the body also having a forward portion and a rearward portion and a maximum above ground height; 
 a face positioned at the forward portion of the body; and 
 a channel defined in the sole adjacent the face and extending into the inner cavity of the club head; 
 wherein the channel has at least 20% of the height of the face; 
 wherein a portion of the sole being located between the face and the channel. 
 
     
     
       2. The golf club head of  claim 1 , wherein the channel has a greatest vertical dimension of least 30% of the height face. 
     
     
       3. The golf head of  claim 1 , wherein the coefficient of restitution measured at a center of the face is 0.80 or greater. 
     
     
       4. The golf club head of  claim 1 , further comprising:
 one or more weight ports formed in the body; and 
 at least one weight configured to be retained at least partially within one of the one or more weight ports. 
 
     
     
       5. The golf club head of  claim 1 , wherein the face is formed of a maraging steel having a composition that includes about 18% to about 19% nickel, about 8% to about 9.5% cobalt, and about 4.7% to about 5.1% molybdenum. 
     
     
       6. The golf club head of  claim 1 , wherein the body being formed of stainless steel and the face being formed on a non-stainless steel. 
     
     
       7. The golf club head of  claim 1 , wherein the channel includes an added weight received in the channel. 
     
     
       8. The golf club head of  claim 7 , wherein there is at least one gap between the added weight and at least one adjacent surface. 
     
     
       9. The golf club head of  claim 8 , wherein the at least one gap provides a flexible boundary. 
     
     
       10. The golf club head of  claim 1 , wherein the CG projection is lower than about 2.0 mm above a center of the face. 
     
     
       11. The golf club head of  claim 1 , wherein the CG projection is lower than about 1.0 mm above the center of the face.
